Hi
There are some questions when using progreSQL8.4.2. I don't sure this
problem is bug.The detail is following:
I make a client program that communicate with progreSQL by ODBC on
Windows7. After running serveral months, this client program is hung
at 00:01 in 2011-11-26 , and become OK after 8 hours.When becoming OK,
client program log message is following:
2011/11/26 08:38:05.527, : SQL ERROR: GetSelectRowNum:
No response from the backend;

2011/11/26 08:38:05.527, : SQL ERROR: GetSelectRowNum: State:42601,Native:26
2011/11/26 08:38:05.527, : SQL ERROR: GetSelectRowNum:
Could not send Query(connection dead);

I don't know how to solve this problem. Someone can explain this
problem cause.Thanks
I'd say you had a connectivity drop-out, and it only recovered when your
TCP/IP connection timed out. Reduce your TCP/IP timeouts and/or enable
keepalives if you have an unreliable network connection between client
and server.
If that's not the case, then more detail please. Where do the client and
server run (same machine?)? How are they connected? etc.
